GEARIN'G.

To all whom it may concern:

Be it known that I, ANDREW J. MOLEN- DON, a citizen of the UnitedStates, residing at Edith, in the county of Coke and State of Texas,have invented a new and useful Gearing, of which the following is aspecification.

This invent-ion has reference to horse powers, and is designed toimprove the construction thereof and the utilization of the powerobtained therefrom.

The objects are to provide a. machine of this type and character fromwhich vary ing rates of speed may be obtained and which may operatethrough the instrumentality of a horse or like animal or which may beotherwise motor driven.

lVit-h the above and other objects in view, the present inventionconsists in the construction, combination and arrangement of parts, allas hereinafter more fully described, specifically claimed andillustrated in the accompanying drawings, wherein,

Figure 1 is a plan view of my power creating device adapted to beoperated by a horse. Fig. 2 is a longitudinal section taken along line22 of Fig. 1. Figs. 3 and 4 are modifications of the driving meansshowing the provision of a gas engine carried by the sweep.

Reference being had to .the drawings, 1 indicates a circular beam whichmay rest on or be partly buried in the ground having securely attachedto its upper face'the metallic track 2 upon which rotates the supportingwheel 3. This wheel is secured to a shaft 4 which is journaled on andcarried by the sweep '5, the outer end of the sweep being therebysupported by the wheel 3 and its inner end by a pillar 6 located at thecenter of the circle formed by the track. The said inner end of thesweep consists of a pair of arms 7 and 8 extending from and pivotallyengaging the pillar 6. The shaft 4 carried by the sweep is journaled ina bearing 9 at the outer end thereof and in the upright portion 10 ofthe arm 7.

Keyed to the pillar 6 is the inner collar or supporting drum 11 having acasing 12 thereon, access to the said casing being obtained throughopenings 13 provided in the base and upper plate thereof. Located inspaced relation to this cent-rally located hollow drum are theconcentrically disposed bands 14, 15 and 16, respectively, the outerpair of said bands 14 and 15 being con- Specification of Letters Patent.

nected by a series of stub machine bolts 17 in such a manner that theyare firmly secured together. At regular intervals about the same thereextends from the outer band 14 through the intermediate bands 15 and 16to the collar 11 the stays 18 which rigidly secure the outer bands 14and 15 to the collar. A similar construction is prbvided between thedrum 11 and the inner band 16, the bolts and stays in conjunction withthe bands between which they extend constltuting a pair of concentrichorizontally disposed ring gears C and B.

A pair of arms 19 project downward from the under face of the lower arm8 of the sweep 5, and carry therein a stub shaft 20, said shaft forminga support for a spur gear 21 which engages the machine bolt-s 17extending from the inner band 16 to the drum 11 and meshes with asimilar gear 22 secured to the inner extremity of the shaft 4 whichplays in the space between the arms 7 and 8. Thus when the sweep isdrawn around the pillar 6 as a center, the wheel 3 will be caused totravel over the track 2 and by its engagement therewith will be rotated.The rotation of the wheel 3 will be transmitted directly to the shaft 4and from the same to the gear wheels 21 and 22. The inner horizontalgear wheel B is thus set in motion and, consequently, a similar motionis imparted directly to the outer wheel C.

Mounted between the track 2 and the supporting beam 1 is the powertransmitting shaft 25 having at its inner extremity the spur gear 26 andat its outer extremity the power pulley (or crank) 27, the latter beingof a construction which will permit either a belt or a pitman to besecured thereto. The spur gear 26 engages the machine bolts 17 betweenthe outer bands 14 and 15 and is thereby rotated so as to transmit powerthrough the shaft 25 to the operating pulley 27.

At regular intervals about the periphery of the outer band 14 arelocated the guide rolls or pulleys 28 mounted in supports 280 and whichnot only facilitate the rotation of the concentric ring gears B and C,but guide and support the same in a manner which increases thedurability and strength of the machine. These rolls, if preferred, maybe doubled and secured at each side of the band to prevent anydisplacement thereof on the pillar 6.

From the foregoing it may be readily seen that upon attaching a horse tothe Whittle tree 29 carried on one side of the sweep '5, the sweep maybe rotated without weight on the animal owing to the presence of thewheel 3 and track 2, thus rotating the concentrically disposed wheels Band C with the result that the spur gear 26, acting through the shaft25, will operate the power pulley 27, thus transmitting power by anydesired means to the adjacent machinery.

The motive power may be increased, if so desired, as shown in Figs. 3and 4, by a gear 30, secured on the end of the shaft 4 around the hub ofthe traction wheel, revolved by meshing with a gear 31 carried on thedrive shaft 35 of an engine 32. This engine is supported by a brace orplatform 33 rigidly secured to the sweep 5, the said brace beingsupported at its outer extremity by a roller or similar traction wheel34, the said traction wheel operating directly in the rear of the largetraction wheel 3. Furthermore, it can readily be noticed that bychanging the sizes of the gears 21 and 22 the speed at which theconcentrically disposed wheels B and C rotate may be controlled,likewise the number of revolutions of the power transmitting shaft.

Horse power machines of this type are commonly employed for drivingmerry go rounds or other small pieces of machinery, and the constructiondescribed avoids the usual objection that the horse in his trip aroundthe circuit must atleast once step over a shaft. The shaft 25 in thisdevice is located practically flush with the surface of the earth, andmight even be lower without departing from the spirit of my inven-Copies of this patent may be obtained for five cents each, by addressingthe Gommissioner of Patentstion; and yet the sweep 5 is purposelyelevated so that the whiflle tree 29 is in convenient position forattachment of the draft animal and his pull thereon has no tendency tolift the wheel 3 off the track. WVith the machine set up and running andconnections to the work already established, it frequently happens thatthe work is increased (as by an excess of patronage of the merry goround) or the horse goes lame, and in such cases it becomes desirable toadd power to the strength of the horse or to substitute motive power forhis work. The construction illustrated in Figs. 3 and 4: affords meanswhereby this can be quickly accomplished, for it is only necessary tostart the engine 82 and the connections with the work being done neednot be interrupted.

Having thus described my invention, what I claim is:

A power transmitter comprising a member rotative in a horizontal plane,gearing carried by the member, a series of concentric circular bandsarranged below the gearing, a series of radial bolts connecting theouter bands, a series of similar bolts connecting the inner bands andengaged by the gearing, means extending from the outer to the innerbands for rigidly connecting the parts, and gearing actuated by theouter series of bolts.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
